Patent MX-9803454-A (MX)
Title: Methods of making fused particulates by flame fusion.
Inventor: CASTLE RICHARD B
IPC: C03B19/10
Filed: 1996-10-31
Abstract: The disclosure describes methods for producing bulk, particulate material that includes solid, generally ellipsoidal particles. Irregularly shaped feed particles with average particle sizes of up to 25 microns on a volume basis are dispersed in at least a portion of a combustible gas mixture by application of force and/or fluidizing agents. The combustible mixture with particles in suspension is then delivered, while controlling agglomeration or re-agglomeration of the particles, to at least one flame front. There, the mixture and suspended particles are uniformly distributed across the surface(s) of and passed through the flame front(s) with a high concentration of particles in the mixture. This flame front and the resultant flame(s) with suspended particles are located in at least one "wall free" zone. In such zone(s) the flame(s) may expand while the particles are maintained in dispersion and heated, with controlled and highly efficient application of heating energy. At least partial fusion occurs within at least the surfaces of the particles at high thermal efficiencies, while agglomeration of particles during fusion is inhibited.

Title: Process for producing pure melamine.
Inventor: CANZI LORENZO
IPC: C07D251/62
Filed: 1998-06-04
Abstract: The invention concerns a process for producing pure melamine in which liquid, ammonia-containing melamine is rapidly expanded from an ammonia partial pressure p1 of between 400 and 50 bar to an ammonia partial pressure p2 of between 200 bar and atmospheric pressure at a temperature which is between 0 and 60 degree C above the fixed point of the melamine which is dependent on the prevailing ammonia partial pressure in each case, higher pressures permitting a greater margin of the temperature from the fixed point of the melamine than lower pressures, and p1 always being greater than p2. As a result thereof, pure melamine is deposited in solid form. Further expansion of the melamine to atmospheric pressure, if necessary, and cooling to room temperature are then carried out in any order and the pure melamine is isolated.

Title: A method for direct manipulation and visualization of the 3d internal structures of a tubular object as they are in reality without any noticeable distortion
Inventor: CHAO-YU CHEN
IPC: G06T19/00
Filed: 2022-02-28
Abstract: In many applications, the assessment of the internal structures of tubular structures (such as in medical imaging, blood vessels, bronchi, and colon) has become a topic of high interest. Many 3D visualization techniques, such as "fly-through" and curved planar reformation (CPR), have been used for visualization of the lumens for medical applications. However, all the existing visualization techniques generate highly distorted images of real objects. This invention provides direct manipulation based on the centerline of the object and visualization of the 3D internal structures of a tubular object without any noticeable distortion. For the first time ever, the lumens of a human colon is visualized as it is in reality. In many medical applications, this can be used for diagnosis, planning of surgery or stent placements, etc. and consequently improves the quality of healthcare significantly. The same technique can be used in many other applications. 1044271

Title: Copolymerisation of sterically unhindered conjugated
IPC: C08F22/04
Filed: 1969-06-27
Abstract: Continuous solution polymersn. of maleic anhydride and an unhindered conjugated diene RCH=C(R')-C(R")=CHR'" with simultaneous introduction of reactants. The molar ratio of diene: maleic anhydride is 1.2-1 to 0.8:1. The diene may be butadiene or isoprene. The copolymer is free of gel, is obtained in high yield, and has desirable characteristics. Excess of maleic anhydride is eliminated, whereby tendency to cross-linking and gel formation is prevented or reduced. The process is suitable for large-scale production, as the added stream of reactants absorbs the liberated heat of polymerisation.

Patent NL-8005023-A (NL)
IPC: F28G13/00
Filed: 1980-09-05
Abstract: A method is described of operating heat-exchanger apparatus comprising a plurality of heat exchanger units which are connected together in series for countercurrent flow of respectively a first heat exchanging medium which contains fluidizable particulate material and a second heat-exchanging medium. Each said unit comprises at least one vertical tubular duct in which said first heat-exchanging medium flows upwardly with said particulate material in a fluidized state and a compartment through which said second heat exchanging medium passes and through which said duct extends. The particulate material acting to remove deposits formed on the tube inside walls by the first medium. In order to achieve cleaning of the tubes in cases where a high rate of deposit occurs, flow of said second medium through each of the compartments is intermittently interrupted for a period of time, while flow through at least one other of said compartments is maintained. Thus the cleaning effect of the particles is increased in the tubes of the compartment for this period of time.
